Thruster InstallationThruster InstallationCorrect thruster installation is critical to ensure optimal
performance.
Fixed tunnel installations should consider, minimum depth of
immersion, proximity of the propellers to the end of the tunnel,
tunnel edge radius, grill design, anode placement and more.
Retracting thruster installations should also consider, minimum
depth of immersion, clearance of the deployed tunnel from the
hull opening, proximity of other appendages and other factors.
OMS is always available to provide guidance on the most
effective installation of our of thrusters.

Tunnel ThrustersTunnel ThrustersOMS Thrusters
T Series tunnel thrusters are compact and easy to fit units that can be supplied complete with steel, aluminium or composite tunnels, pre-drilled ready for installation.
The thruster hub units are protected by twin shaft seals on each propeller shaft, and a single shaft seal on the vertical input shaft. The tunnel thruster uses high torque spiral bevel gears and twin contra-rotating propellers to develop a high thrust to tunnel diameter ratio.
T Series thrusters are supplied complete with a mounting saddle, all gaskets / fasteners and a suitable interface for any hydraulic or electric motor. The motor is driven via a flexible coupling to reduce noise and vibration.
1. For hydraulic thrusters: a hydraulic fixed displacement gear motor or bent axis motor, suitable for open and closed loop applications.
2. For electric thrusters: a large range of standard motors with multi ple voltages / frequencies are available. Also a range of permanent magnet motors that are compact and lightweight can be supplied for the same thrusters. Supplied flange or foot mounted for horizontal or vertical installation.
3. Aluminium bronze (AB2) cast hub with fill and drain ports.
4. Twin contra rotating aluminium bronze (AB2), four-blade matched specifically for the power requirements of the thruster.

Vertical Retracting ThrustersVertical Retracting Thrusters OMS Thrusters
V Series vertical retracting thrusters benefit from the same in-hub technology as our T Series thrusters, whilst allowing the thruster to fully retract leaving a fair hull with minimal drag. This compact design uses a lead screw lift assembly with a reduction gear box to ensure that the thruster hub, when retracted, is held firmly in place.
The vertical thruster is also very useful where vessels have a deep V profile so the thruster is fitted higher providing a longer deployment stroke to clear the hull. They can also be fitted further forward or aft than a conventional tunnel thruster increasing the turning moment of the hull and therefore requiring less power input.
For added security all V Series thrusters can be manually raised or lowered in case of power failure. To ensure there is no environmental risk, the main drive motor, hydraulic hoses and electric cables are inside the vessel so are not open to sea water.
1. For hydraulic thrusters: a fixed displacement gear motor or bent axis piston motor, suitable for open and closed loop applications. These motors benefit from good overall efficiency, excellent starting torque and a very compact design.
2. For electric thrusters: a permanent magnet motor. These motors benefit from extremely compact and robust structure, high efficiency and liquid cooled with plain water or water/glycol mixture.
3. Fabricated base plate / bearing assemblies with hole patterns, compliant to all classifications.
4. Ratio gearbox driving a trapezoidal threaded lead screw ensuring self-weight support of the thruster. Raise / lower limit switches and indicators. Twin lead screw used on 500 Series.
5. Aluminium bronze (AB2) or aluminium cast hub with fill and drain ports.
6. Twin contra rotating aluminium bronze (AB2), four-blade propellers matched specifically for the power requirements of the thruster.
7. A matched set of spiral bevel gears (two x crown wheels, one x pinion gear) are supported on super duplex stainless steel propeller and input shafts.

Our vertical 360° rotating thrusters benefit from the same in-hub technology as the fixed tunnel thruster, whilst allowing the thruster to fully retract leaving a fair hull with minimal drag. This type of thruster has a very small footprint so is ideally suited to installation in aft or fore lockers where space is at a premium.
The vertical rotating thruster is also very useful where vessels have a deep V profile so the thruster is fitted higher providing a longer deployment stroke to clear the hull. They can also be fitted further forward or aft than a conventional tunnel thrusters increasing the turning moment of the hull and therefore requiring less power input.
This type of thruster uses a vertical lead screw and guide rods to raise and lower the unit via a motor. As with the swing thruster, all motors and hoses are concealed within the vessel so are not in direct contact with sea water. OMS has worked with a number of boat builders to optimise the range offered. The rotate mechanism allows you to position the pod and provide 360 degrees of thrust.
The OMS rotating thruster has also been installed and used as emergency propulsion.

Swing ThrustersSwing Thrusters OMS Thrusters
The swing thruster benefits from the same in-hub technology as the fixed tunnel thruster, whilst allowing the thruster to fully retract leaving a fair hull with minimal drag. These types of thrusters are usually used in applications where they are positioned within the accommodation area of a vessel. The low profile and compact design allows them to be easily fitted below floor bearers or in low level lockers, under beds or among other locations. This compact design uses a lead screw lift assembly with a reduction gear box to ensure that the thruster hub, when retracted is held firmly in place and cannot move. In addition, OMS swing thrusters feature a locking pin which adds additional security when locking the leg in the raised position. The main drive motor and hydraulic hoses or cables are fully enclosed within the upper leg assembly so are not open to sea water. OMS have worked with a number of boat builders to optimise the range offered.
Technical DetailsTechnical Details OMS Thrusters
1. For hydraulic thrusters: a fixed displacement bent axis axial piston hydraulic motor, suitable for open and closed loop applications.
2. For electric thrusters: a permanent magnet motor. These motors benefit from extremely compact and robust structure, high efficiency and liquid cooled with plain water or water/glycol mixture.
3. All boxes can be pressure tested to classification rules. Fabrication by coded welders.

Fixed Drive LegFixed Drive Leg OMS Thrusters
Technical DetailsTechnical Details OMS Thrusters
D series fixed drive legs are a range of the most compact, lightweight and versatile units available on the market. They have been developed from the same technology used in our range of steerable and retracting thruster and drive designs.
The drive leg can be connected via a coupling to a traditional diesel engine, hydraulic or electric motor. The legs are designed to be simple to install, easy to maintain and provide a compact solution. Designed to work with large fixed or folding props, the OMS drive leg is suitable for sail and powerboat applications. The standard leg comes with a 2:1 ratio however OMS is able to customise the gears, powering and length/depth of leg to suit.
1. Electric, hydraulic or diesel shaft driven.
2. Available as a high performance upgrade to replace existing saildrive installations. Lower leg assemblies are available separately to interface with existing inboard components.
3. A matched set of spiral bevel gears supported on super duplex stainless steel propeller and input shafts. Gear ratios can be adjusted to suit specific drive input requirement. Propeller shaft can be matched to any brand of fixed or folding propeller.
4. Anti-vibration mounting for smooth and quiet operation.
5. Double hull gasket and water sensor for added security.
6. Breakaway design feature to prevent hull damage on impact with debris.
7. Aluminium or Titanium leg and underwater components, aluminium elsewhere. Other materials available on request.
8. Capable of regeneration with a suitable electrical system.
9. Drive leg lubrication/oil change system to allow oil to be changed and circulated whilst afloat.
10. Flexible coupling between hub assembly and hydraulic/ electric motor to reduce noise and vibration.
11. Factory test and inspection reports provided with all units.
